l RAIL JOINT AND IASTENER.

Specification of Letters Patent.

Application led December 17, 1921. Serial No. 523,046.

ToaZZ whom t may concern:

Ee it known that l, IGNATZ MIENTKiEwICZ, a citizen of Poland, residing at W'aterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Rail Jointsy and Fasteners, of which the following is a specification.

This invention relates to certain new and useful improvements in rail joint and fastener, and has particular reference to the idea of securing the meetingends of rails to a joint chair without the employment of fastening bolts.

The primary` object of the invention resides in the provision of a rail joint and fastener wherein the joint chair supporting the meeting ends of rails, carries a cam shaft adapted to be moved into engagement with the rails to anchor the same to the chair.

A further objectief the invention has reference to a rail joint and fastenerl wherein a chair supporting the meeting ends of rails, has a longitudinally extending cam shaft journaled therein with a splice bar intern posed between the cam portion of the shaft and the rails to be engaged by the cam for holding the rails anchored in the chair, cooperating rack teeth formed on the cam and splice bar to prevent rotation of the cam shaft when the same is moved to a locked position with respect to the rails W' ith these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination Vand arrangements of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding throughout the several views,

Figure 1 is a top plan view of a rail joint parts and fastener constructed in accordance withr j same,

Figure 3 is an end elevational View of the rail joint and fastener showing the cam shaft of the fastener interlocked with the `splice bar.

Figure` 4 is a cross sectional view taken on lines IV`IV of Figure 1, showing the cam shaft journaled in the chair and mterlocked with the splice bar,

Figure 5 is across sectional view taken on line V-V of Figure 1, showing the cam shaft engaging the splice bar for moving the same into engagement with the rails,

Figure 6 is a detail sectional view showing the position of the cam shaft when the splice bar is inserted in the joint chair, and

Figure 7 is a vdetail sectional view of a modified -form of the invention showing an anchoring foot for the splice bar, received in anopening provided in the rail chair.

Referring more in detail to the accompanying drawings there is illustrated a oint chair and fastener for railroad rails the joint chair including a bottom wall 1 supported on cross ties 2 and having integral outer side rail-engaging flanges 3 for overlying andvengaging the base flanges of the rails 4, the verticalwebs 3 of the iianges 3 engaging the webs of the rails 4 and having spaced pins 5 `extending through openings G in the webs of the rails, the meeting ends of the rails being received on the bottom wall 1 of the chair with the pins 5 of the flange webs 3a received in the rail web openings to prevent longitudinal movement of the rails relative to the chair.

As clearly shown in Figs. e to 6 the bottom wall 1 of the chair has a side extension 1a opposite therail-engaging Hange a perpendicular inwardly curved outer side wall 7 being carried by the extension wall 1ZL with bearings 8 formed at the ends of the wall 7 for purposes presently to appear.

A longitudinally extendingY shaft 9 having a key end 9a is ournaled in the end bearing 8 of the side wall 7, the shaft 9 having a cam 11 secured thereto, or formed as an integral part thereof, intermediate the ends, the cam 11 when in the position shown in Fig. 6 being spaced from the rails 1 a sulicient distance to permit the insertion of splice bars.

A splice bar 12 of the form best illustrated in Figs. el to 6 is positioned in the joint chair intermediate the cam shaft and the rails 4, the splice bar carrying pins 13 to be received in openings formed in the webs of the rails 4.

The splice bar 12 is placed in position as indicated in Fig. 6 and with the shaft 9 in the dotted line position shown in Fig. 1, said shaft being rotated to cause the cam l1 soV .to engage the splice har 1Q and move the same into intimate engagement with the faces of the rails 4, and positioning the pins 13 in the rail web openings. Y, f

In order to prevent rotation of the cam shaft when the same is moved to engaging position with the splice har, the outer 'face of the splice bar, at the `end thereof spaced from the key end 9a of the rod is provided with a vertical roiv of horizontally extending rack teeth 14, While vthe adjacent end Vof the cam 11 is provided with similarly formed rack teeth 15, the rack teeth le" and 15 being interengaged hy longitudinally shifting the shafts 9 and cam 11 carried thereby, the 'engaging teeth preventing rotary movement ofthe shaft 9' and effectively holding the meeting ends of the rails e properly assembledin the joint chair.

lNhen the teeth 1li and 15 are engaged, the end 9 of the shaft extends outwardly of the adjacent end Wall S for the reception of a Cotter pin 1G to hold the cam. shaft in its locked position, and to prevent shifting movement thereof with a consequent disengagement of the teeth la and 15.

Should it he desired to remove the rails from the chair, the shaft 9 is shifted longitudinally to cause the disengagement of the rack teeth 1a and 15, at which time the Shaft may he rotated to disengage Vthe cam 11 from the splice har 12, returning the elements to the position shown in Fig.- 6, and at which time, the splice bar l2 may he removed and the rails et similarly disengaged from the flange web 3a of the joint chair. By continuing the longitudinal shifting movement of the shaft 9, the end thereof oppositev the key portion 10 may he removed from its end bearing S, this movement being'permitted hy the relatively'large hearing in the end Wall 8 adjacent the key end 10 of the shaft. The shaft is then reversed Vin movement for entirely displacing the same from the chair.

A modified form of the invention is shown in Fig. 7, Awherein th elements of construction are similar to the preferred form, with f ing 18 provided in the hottom Wall 1 of the joint chair, this engagement preventing creeping movement of the splice har relative to the chair and may also he employed in connection with the pins 13 illustrated in connection With the preferred form.

Vilhile. the form of the invention herein shown and described is what is'helieved to he the preferred embodimentY thereof, it is nevertheless to he understood that various forms, modifications and arrangements of the parts may be made VWithout departing from the spiritl and scope Vof the invention as claimed.

1What I claimrilsc* y 1. A rail joint and fastener comprising a chair, meeting rail endssupported in the chair, a removable splice har engaging V'one side of the rails positioned in the chair, a cam shaft journaled in the chair adapted to engage the splice har to move the same into engagement with the rails, and cooperating means carried by the splice har and cam shaft adapted for engagement when the cam shaft is longitudinally shifted, to prevent rotary lnovement of the cam shaft.

2. A rail joint and fastener comprising a chair, meetingl rail ends supported thereon, a splice har for the rails, a longitudinally shiftahle shaft journaled in said chair and a cam carried by said shaft adapted to engage the splice bar toV move lthe same into engagement With the rails for anchoring the rails to the shaft. i

3. A rail joint and fastener comprising a chair, meeting rail ends supported thereon,V

a splice bar for the rails, a longitudinally shiftahle shaft journaled in said chair, a cam carried hy said shaft adapted to engage the splice bar to move the same. into engagement with the rails for anchoring the rails to the shaft, and cooperating means carried by the splice bar and cam adapted for engagement when the shaft is longitudinally shifted, to prevent rotation of the shaft.

4l. A rail joint and fastener comprising a chair, meeting rail ends supported thereon, a splice har for theV rails, a longitudinally shiftahle shaft journaled in said chair, a cam carried hy said shaft adapted to engage the splice har to move the sameinto venga'geznent with the rails for anchoring the rails to the shaft7 and cooperating rack teeth formed on adjacent faces of the splice bar and cam adapted forengagement When the shaft and cam are longitudinally shifted, to prevent rotation of the cam.

In testimony whereof I affix my signature.
